To all whom t may concern Be it known that I, JOSEPH REN Avor'rn, a subject of the King of England, and a resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful improvements in Window- Cleaners, of which the 'following is a specification.

The main objects of this invention are to provide an improved form of window cleaner arranged for permanent attachment to a window so as to be operated from the inside for removing water, snow or sleet froml the outside of the glass; to provide improved supporting means for the 'squeegee and the operating handle whereby they may be conveniently attached at any point on the-window sash; to provide an improved construction of the squeegee; to provide improved means for preventing excessive pressure to be exerted by the squeegee against the glass during the cleaning operation; 'and to provide a simple and inexpensive device of this kind which is capable of being conveniently mounted inl any desired position on practically any window sash.

An illustrative embodiment of this invention is shown in'the accompanying drawings, in which:

Figure l is a perspective view of a window showing the' improved form of cleaner attached thereto, the full lines 'indicating the position of the squeegee in its elevated position preparatory. to swinging 1t down wardly for cleaning the glass, the dotted outlines representing the squeegee in its normal position. Fig. 2 is an enlarged longitudinal sectional detail of the cleaner mounting.v Fig. 3 is a reduced lside view of the cleaner showing the parts intheir respective positions during the cleaning operation. Fig. 4 is a similar view showing the relative positions of the parts when the squeegee is being shifted into its elevated positionprearatory to cleaning the window. Fig. d

1s a reduced inside elevation of a window vshowing the arrangement ofthe supporting plate for mounting the cleaner in the upper left hand corner of the window. Fig. 6 1s a similar view showing the arrangement of the plate for mounting the cleaner in the opposite corner. Fig. 7 is an inside elevation of a long narrow window vshowing how the plate is attached to the frame so asto permit the cleaner to be swung through 180 degrees., Fig. 8 is an enlarged detail of the Patented Nov..

sectional detail of the bearing. Fig 10 is an enlarged sectional detail of the squeegee. u In the construction shown in the drawings, a bearing 1 is integrally supported on a .transverse plate 2 by means of which 1t is attached to the window sash 3 so as to support a squeegee et in the desired position'to be' swung across the glass 5 for reA moving water, snow or sleet therefrom. The

`squeegee 4rand an operating handle 7 are connected to opposite ends of a shaft 6 which '1s rotatablyv and shiftably. mounted in the bearing l.

lI`he shaft 6 has ou'rnals formed at its opposite ends which fit within the ends of the. bearing l. At one end the journal is in the form of a bushing 8 and at the other end is in the form of a hub AQlintegral on the handle 7. This arrangement of the journals provides an annular space/10 between the shaft and bearing intermediate the'hnbs 8 and 9 wherein the spring 1l is housed and wherein a quantity of graphite or other lubricating material may be retained for lubrieating 'the journals of said shaft. spring l1 embraces the shaft 6 and lbears against the journal 8 and an annular shoulder 1Q for norinallyurging the shaft 6 to move the squeegee t out of contact with the glass 5. Apertures 13 are formed in the bearing l so as to-permit the passage of air into and out of the annular space The l 104 and prevent the creation of pressure or l vacuum as the shafty is shifted back and forth.y

The operating handle 7 is secured to the shaft 6 by being screwed Onto the end thereof, preferably by means of -a left handed thread, and is locked thereto by means of a nut 14 preferably having a right?v handed thread. A pin 15, carriedby the handle 7, is arranged to engage apertures 16 formed in the opposed face of the bearing Fig. 7.

detachably connected to an arm 21 whichl is shown to be integral with the shaft 4An annular shoulder 22 is formed ontbe shaft (3 inwardlyof the arm- 21 and is arranged. so that the face thereof is located inwardly of the parallel parts of the angle plates 19 so that it will Contact with the end 2l of the bearing` 1 and. limit the axial movement of the shaft 6 and thereby prevent.- the metal of the' squeegee from coming in Contact with the glass and also prevent eX- eessive pressing` of the squeeg'ee il; against the glass 5. l

'The plate 2 is formed of angularly disposed parts 25 and 2G respectively arranged so that the plate .may be secured to the window sash 8 at any one of the corners thereof by attachment to the abutting side bars so as to support the axis of the shaft 6 inwardly of the angle formed by the inner edges of the two side bars'of the window. sash. rlliese parts are also so arranged that the part 26 may be cut oil and the part used to mount the cleaner in the middle of a. long narrow sash, such as indicated in Then mounted 0n the sash, the end 24 of the bearing extends through a hole 27 foi-inedV in the glass and has a rino' 2S secured on the end thereof. Gaskets 29 and 30 of. rubber or other soft material are interposed between tlievglass vand the bearing land the ring 2S sov as to form a closed joint around the hole.

27.' The rin@ 28 and the gasket 30, against which it bears, are formed so that the face 3l of the'end 24: .protrudes slightly' beyond 'said ring. Thus, when the squeegee is 'op i y(ei-ated, the shoulder22 on the arm 21 beaif,A

against the end 24 and the pressure is dr rectly upon the plate 2 so that there is no strain placed upon tli'e y,eglass direct'.

Where the cleaner is mountedon afwindow "which is s hiftable into and out of the frame, a felt or rubber-collar 32 may be placed on the bearing' l to vserve as a buffer ,when the to prev-ent injurytto the frame window is shifted tliereinto.y l

The deviceshown is operated in lowing),` manner: The `:operator 4grasps the handle 'with one hand and pulls thereon to' retract the pinl froinfan aperture 16 so that the: squeegee maybe swung` into a horizontal position as sliowniii1l+` ig;1.. As soon as the shaft has been turnedslightly 'so asf the fol-A j havingr an annular space around 'said shaft' intermediate said journals soas lto"n'ovide' .a ret acted position, aid. bearing liavinglyan.

i ,soenna to prevent the pin 15 from rentering the aperture 1G, the pull on the handle is released and the pin 15 bears on the opposed face of the bearing'. This' allow/s thev squeeeee to be swung into said horizontal position without bringing' the rubber strip 17 .i nto contact with the glass. Except' for` this arrangement of the pin the operatorwoulcl have difficulty in swinging the squeegee into its elevated position without sweepingthe glass onthe lip-stroke, and theirZ on the re' turn stroke the material collected on the upstroke would smear the glass on said return movement. The squeeogee is their' urged against the glass 'and by means of thehun dle T swung' downwardly across the .win

dow so as to remove whatever .may be ao.

cuinulated thereon, such as snow, rain or sleet. lVheii the swinging movement is com.- pleted, they handle 7 is released and the springll shifts the shaft G'axiallv so as to move the squeegee -l out of contact with the dass and cause the rengagement of the pin 15 with the aperture 1G. ,The cleaner is thereupon. vlocked inV its normal position, andthe water thereon is allowed to run down ai drain olf the bottom thereof. i

l. ltliougli but one specific embodiment of this invention has been herein shown and described, it will be understood that numerous details of the construction shown may be altered. or omitted without departing from the spirit of this invention. as defined by the following claims. Y
